| Résumé : | Near infrared spectra of a carbon dioxide sample enriched with oxygen-17 have been recorded using a high resolution continuous scan Fourier transform interferometer fitted with a femto OPO laser source. Cavity enhanced absorption has been achieved in a static gas cell allowing for an optimal rms noise equivalent absorption of 4.4 × 10-9 cm-1 Hz -1/2 per spectral element to be reached, corresponding to αmin = 3 × 10-7 cm-1. The 3ν1 + ν3 and related hot bands in 12C17O2 and the 3ν1 + ν3 R-branch in 12C17O18O have been identified and rotationally analyzed. © 2011 Elsevier B.V. All rights reserved. |
